object of type 'int' has no len()

[cwnuyangyan]

I run this demo, but face a error in the line of 673 of deformable_detr.py,
domain_levels += len(args.hda)
args.hda is int, so Exception has occurred: TypeError object of type 'int' has no len()

SFA/main_da.py

Line 102 in 3a0725f

parser.add_argument('--hda', default=None, type=int, nargs='+',

With nargs='+', args.hda should be a list if it's not None.

Please provide more details about your running command, so I can better understand your issue.
